EMILE L. CUENDET, OF NEW YORK, N. Y.

FEED MECHANISM FOR MECHANICAL MUSICAL INSTRUMENTS.

SPECIFICATION forming part of Letters Patent No. 589,421, dated September 7', 1897.

Application filed September 21, 1896. Serial No. 606,467. (No model.)

To all whom it may concern:

Be it known that I, EMILE L. OUENDET, a citizen of the Republic of Switzerland, and a resident of New York city, New York, have invented an Improved Feed Mechanism for Mechanical Musical Instruments, of whic the following is a specification.

This invention relates to an improved feed mechanism for mechanical musical instruments by which a positive engagement between note-plate and drive-wheel and a consequent uniform feed is effected.

In the accompanying drawings, Figure 1 is a plan of portion of a note-plate adapted to be engaged by the feed mechanism. Fig. 2 is a detail longitudinal section through the feed mechanism on line 2 2, Fig. 3; Fig. 3, a section on line 3 3, Fig. 2; and Fig. 4, a detail perspective view of the bottom of the noteplate, showing a number of the driving-teeth.

The letterArepresents a circular revoluble note-plate for mechanical musical instru ments provided with suitably-constructed reed-actuating pins or teeth. I11 order to impart the proper feed motion to the plate A, itis provided with the peripherally-arranged driving-teeth a, which are embossed, as shown, to form a series of bulged projections. Each tooth is at its working edge severed from the body of plate A, as at a so as to form an arched free edge a in line with the radius of plate A. The teeth a are adapted to be engaged by a drive-wheel B, composed of a pair of outer disks or cheeks b b and of a number of transverse connecting-pins b.

ll hile the pins 1) are adapted to engage the severed edges a of teeth a, the disks 1; will engage the lower face of the disk A to the right and left of such teeth, as shown. Directly above the wheel B there are mounted upon a transverse shaft a pair of pressurerollers C, having tapering rims, so that the bodies of such rollers clear the cavities of the teeth a. The treads of the rollers C are placed directly above and are in vertical alinement with the disks b, so that in this Way the sheet A is positively engaged by the parts I) C at both sides of the teeth.

It will be seen that by my invention a positive engagement between the working edges a of the teeth and the pins 1) is effected, while, furthermore, any buckling or bulging of the sheet is prevented, so that a uniform and reliable feed is imparted to the musicsheet.

Vhat I claim is A feed mechanism for mechanical musical instruments consisting of a music-sheet A, having embossed teeth that are provided with a severed working edge, a pair of disks 1), adapted to engage the lower side of sheet A, at the sides of such teeth, driving-pins Z), connecting the disks, and a pair of pressurerollers O, that are adapted to engage the upper side of sheet A, in vertical alinement with the disks, substantially as specified.
